1.1 This specification covers cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than cold-rolled carbon steel sheet, with specific temper, with specific edge or specific finish, and in sizes as follows:
|Width, in.||Thickness, in.|
|Over 1/2 to 23 15/16||0.300 and under|
|Over 12.5 to 600 mm||7.6 mm and under|
1.2 Cold-rolled strip is produced with a maximum specified carbon not exceeding 0.25 percent.
1.3 Strip tolerance products may be available in widths wider than 23 15/16 in. [600 mm] by agreement between purchaser and supplier. However, such products are technically classified as cold rolled sheet. This specification does not include cold-rolled carbon spring steel, Specification A 682/682M. The tolerances, finishes, tempers, edges, and available widths and thicknesses differentiate cold rolled strip from the product known as cold rolled sheet which is defined by Specification A568/A568M and Specification A682/A682M.
1.4 For the purpose of determining conformance with this specification, values shall be rounded to the nearest unit in the right hand place of figures used in expressing the limiting values in accordance with the rounding method of Practice E29.
1.5 The SI portions of the tables contained herein list permissible variations in dimensions and mass (see Note 1) in SI (metric) units. The values listed are not exact conversions of the values listed in the inch-pound tables, but instead are rounded or rationalized values. Conformance to SI tolerances is mandatory when the "M" specification is used.Note 1--the term weight is used when inch-pound units are the standard. However, under SI the preferred term is mass.
1.6 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems will result in nonconformance with the specification.
1.7 This specification is expressed in both inch-pound units and SI units. However, unless the order specifies the applicable "M" specification designation (SI units), the material shall be furnished to inch-pound units.
